NAME

     getpid, getppid -- get parent or calling process identification

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/types.h>

     pid_t
     getpid(void);

     pid_t
     getppid(void);

DESCRIPTION

     The getpid() system call returns the process ID of the calling process.  Though the ID is guaranteed to be unique, it should NOT be used for
     constructing temporary file names, for security reasons; see mkstemp(3) instead.

     The getppid() system call returns the process ID of the parent of the calling process.

ERRORS

     The getpid() and getppid() system calls are always successful, and no return value is reserved to indicate an error.

SEE ALSO

     fork(2), getpgrp(2), kill(2), setpgid(2), setsid(2), exec(3)

STANDARDS

     The getpid() and getppid() system calls are expected to conform to ISO/IEC 9945-1:1990 (``POSIX.1'').

HISTORY

     The getpid() function appeared in Version 7 AT&T UNIX.
